Question

What are the main components of tristyrylphenol ethoxylate 600-1?

Answer

Tristyrylphenol ethoxylate 600-1 is a high-performance nonionic surfactant with tristyrylphenol as the hydrophobic group and polyoxyethylene ether as the hydrophilic chain segment, with an active ingredient content of over 99%.

Detailed Description

The main component of this product is polyoxyethylene tristyrylphenyl ether, with the chemical structure formula C₆H₅C(C₈H₈)₃O(C₂H₄O)ₙH. From the product composition, it is a single-type nonionic surfactant, not a blended mixture. The product appears as a light yellow to brownish yellow viscous liquid or paste, with a core component content (solid content) of ≥99%, and the content of unreacted substances such as free alcohols is controlled below 1%, ensuring extremely high chemical purity.

At the molecular level, this component is constructed from two key parts: the hydrophobic end is a rigid, bulky tristyrylphenol (also known as triphenylethylphenol) structure, providing excellent steric hindrance effect; the hydrophilic end is a flexible polyoxyethylene ether long chain (with a degree of polymerization n approximately equal to 1, corresponding to CAS number 99734-09-5, molecular weight about 449). This unique chemical structure gives the component excellent chemical stability, maintaining good activity under acidic, alkaline, and high-hardness water conditions.
